leftward

The word 'leftward' is a directional term formed within English by combining the native root 'left' with the directional suffix '-ward'. The Old English root lyft originally carried connotations of weakness or misfortune, reflecting a historical bias against the left side, which was considered the 'sinister' or inferior side. The suffix '-ward', from Old English -weard, is related to the verb 'weorþan' (to become) and denotes a turning or facing toward a specific point. Thus, 'leftward' literally means "oriented or moving in the direction of the left side," its modern meaning shedding the ancient negative associations of its root while retaining the purely spatial sense.
